I'm still a little lost by the point of it. I know it showed up in the following season for a little bit, but the reasons behind it are still a bit confusing to me. Why did they have a TARDIS as apposed to any other time machine? Why was it on Craigs roof? When this was on I expected payoff and when it never came I'd already forgotten about it, but on rewatch it stood out that it didn't really go anywhere.
